I mean, I agree, but Maya was never a good person insofar as Akira hasn't been one either. It's more that our Maya has been enduring resets for like a 1000 cycles out of love for him, and that shifts the scales a lot. Being extremely jaded because of that also helps with giving her a pass on lots of stuff she did.
But everything anyone has ever pointed out about Maya before the resets either ranged from being a bad person to outright criminal (Ami points out how she's been lying to her since forever, Noriko hints at some very fucked up shit she may have done to Akira when he ghosted her, and Happy Events seem to suggest that as well). So I'm actually very excited every time new Maya shows up, since it lets me learn a lot more than what our Maya could show.
